We may not all have the same taste in movies, but at the most basic level, we may at least have the same response. A new study looking at the brains of people as they watch movies found a striking similarity among their brain patterns.

Researchers at Aalto University in Finland conducted the study by having the participants watch At Land (a silent film from 1944), while monitoring brain activity. Instead of using the traditional fMRI, however, they used magnetoencephalography (MEG), which the researchers say was able to catch much faster brain activity than other methods.

What they found was that, when viewed in increments of fractions of seconds, the activity of their participants seemed to spike and flatline in roughly the same patterns, as you can see in the above image where the participants activity graphs (in blue) are overlaid.

It's still pretty early to start drawing conclusions about just how much movies can synchronize what happens in our brain, but it's definitely something to think about next time you grab a seat in a crowded theater.
